WAGON-DUIVIPING MECHANISM.

an Improved Wagon-Dumping Mechanism,

of which the following'is a specification.

The object of my invention is to provide an improved construction of mechanism for dumping or tipping wagons more particu larly of the type in which it is desired to provide for crossing .the wagon over the tilting platform or cradle when dumping.

In the accompanying drawings, Figure 1 is a side elevation of my improved mechanism. Fig. 2 is a'plan view of the same. Fig. 8-is a transverse section on the lines 3 3, Fig. 2,

desired without drawn to a larger scale; and .Figs. stand .5

show details.

I mount the supporting frame A upon wheels at a to travel on tracks 2. r, so that the whole apparatus may quickly and easily be moved from one position to another; but when .its position has been determined'this carriage A is fixed for the time being. In the present instance this frame A is shown as built up of side beams a a and end cross-beams a a butit may be constructed in any suitable way. On the opposite sides of this open frame are mounted the upright brackets or bearings A A, in which I mount the trunnions. of the I tipping platform'or cradle B, which is shown as consisting of side brackets b 6 and crossbars b- V. on which are supported the longitudinal rails R R to receive the dumping wagon W. The rear ends of, these. rails R B when in horizontal ,positionrest upon the cross-beam. a of the frame A, Figs. land 2. Beyond the forward endsof the rails are short rail ends R R, secured to the forward crossbeam of of the frame A. As shown by dotted lines in Figs. 1 and 2, tracks R R leadto and from these parts at both ends ofthe frame. I also secure to the brackets Z) 6 flanged plates O O in such a position as to engage either the body or wheels of the truck or wagon W to be dumped. In the drawings I have shown the forward cross-beam 6 of the tilting platform B, I mount a pair of movable stops D D,

as shown in Fig- 4, and are fast upon a shaft E, mounted-in bearings e on the cross-beam 6 When the stop-levers are in their upright position, their horizontal arms bear. upon the up- .per face of the cross-beam b 'to support them against the blow and weight of the wagon. The cross-shaftE, upon which these stops are mounted, is provided with a hand-lever F, by which the shaft may be turned to turn down the stops from the position shown in full lines in Fig. 4: to the position shown by dotted lines in that figure, and by full lines in Fig. 3, so that then the wagon may be run over the tipping-platform to the tracks R beyond. In.

wheel '9, carried" by the pivot of the platform I B, I provide a locking means for the platform controlled by the same hand-lever F- which manipulates the stops D, so that the same movement of this hand-lever which throws the stops D out of the way serves to throw the locking means into action to lock the platform in horizontal position. For this pu'rpose'I provide suitable guides G in the tilting platform (in the case shown at the forward ends of the side brackets Z2) for the laterally-sliding bolts G, and on the two side bars of the frame A, I provide keepers H (each in the form of a stirrup, Fig. 1) to re-' ceive these lockingbolts G. To actuate these locking-bolts, I provide on the opposite ends of the shaft E cylindrical heads c 6 with cam-grooves 6, into which project pins 9 on the interior of the bolts. These latter are made hollow to slide. over the ends of the heads 6. These camgrooves are such that when the shaft E is turned by the hand-lever F to throw the stops D down, and out of the way of thewagon-axles the bolts G G will be positively thrown outward laterally andthe other hand, when the shaft E is turned to throw the stops up into the position shown by full lines in Fig. 4 to arrest the car to be dumped the bolts G will be withdrawn from the keepers H and the tilting platform be free to be tilted, subject to the control of the brake.

I claim as my invention 1. The herein described mechanism for dumping-Wagons, comprising a frame, a tilting platform pivoted to the frame and having rails With movable stops, a locking mechanism for the tilting frame, and lever means to operate the stops and at the same time positively throw the locking-bolts to lock the frame when the stops are moved out of the way, and vice versa. v

2. The combination of a frame, a tilting platform pivoted thereto, stop-levers for the Wagon, a cross-shaft carrying the levers, bolts on the Wagon and keepers on the frame, and
